Thicker replacement grips (like Wilson Cushion-Aire Sponge)

I always buy the Wilson Cushion-Aire Sponge, but I wonder if there are other alternatives I should be considering. I don't want anything that will reduce the grip size. Anybody have a recommendation for a similar but better non-leather replacement grip?

I tried a few Babolat "soft" grips -- but they were just too soft and too puffy.
The closest thing to Wilson air sponge I've seen was the Kirschbaum grip. Kirschbaum is just a tad softer, and has a smooth uniform surface, which I like. I rank both the Wilson AirSponge and Kirschbaum as "medium soft". They are just the right softness for me.
